LEROY G. BINKIEY, OF CHICAGO, ILLINOIS, ASSIGNOR TO RAILWAY & lMINE kSUPPLY COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION 0F ILLINOIS. Y,

MINE-CAR W' HEEL.

To all w hom t may concern Be it known that I, LEROY G. BINKLEY, a citizen of the United States, residing at Chicago, in the county of Cook and State of lllinois, have invented certain new and useful Improvements in Mine-Car Wheels, of which the following is a specification.

This invention relates in general to rolling stock and more particularly to the wheels Vand their manner of attachment on mine cars.

Owing to the sharp curves of the tracks and the irregularities in the track bed `in mines it has been found practically neces sary to mount each wheel of a mine car so that it is independently rotatable on its axle. Various constructions have been employed for attaching the wheels to the axles or to the bearing boxes so as to prevent longitudinal displacements of the wheels in case of' derailment of' the car.

My present invention is concerned more particularly with the attachment of the car wheel to its axle so that it will not become longitudinally displaced in case of derailment or other accident to the car, the primary object of the invention being to produce a locking connection for the wheel which will maintain the wheel in position during operation and which can be released so as to readily permit the removal of a wheel and its replacement by another whenever occasion requires, such for instance, as `the breaking of a wheel itself.

Another object of the invention is to provide a car wheel and its mounting which shall be simple in construction, strong and durable in operation, which will protect the wheel bearing against the entrance of dust and dirt, and which when the wheel is re- `moved will so retain the bearing rollers that they will not become disassociated from their bearing raceway or be free to ldropout on to the dirty floor of the mine.

Other objects and many of the attendant advantages of my invention should be readily appreciated by those skilled in the art as the same becomes better understood by reference to the following description when considered in connection with the accompanying drawings.

Specification of Letters Patent.

Patented Feb. 3, 1920.

Application filed September 26, 1918. Serial No. 255,747.

Referring` to the drawings:

Figure 1 is a longitudinal sectional view through a car wheel and its mounting embodying one form of my invention;

Fig. 2 is a transverse sectional view taken substantially on the line 2;2 of Fig. 1;

Fig. 3 is an end view looking at the inner end of the wheel hub; and

Fig. a is a view similar to Fig. 1 of a modified form of my invention.

By reference to the drawings it will be observed that reference character 5 vindicates generally a fragment of a car body towhich the bearing boxes 6 are securely bolted in the customary manner, the bolt holes through which the fastening bolts pass being indicated by reference character 7. Thisv box, as will be observed from Fig. 1, is cored longi tudinally to accommodate the axle 8 and the outer end of the core is enlarged to receive the hub of the wheel, the inner end of the enlargement being extended into a vcircumferential groove 9 for a purpose which will be later explained.

The axle 8 extends through the bearing box and, as will be understood, also extends entirely across the car and through the companion bearing box on the opposite side of the car 4body where it receives the other wheel. lt is thought, however, that an illustration of a box and its coperating parts at one side of the car will be sufficient for an understanding of this invention. VThe smaller portion ofthe bearing box core is sufficiently larger than the shaft 8 to accommodate a sleeve 10 which snugly lits the shaft 8 and is rigidly secured thereto by a pin 11, as shown.

The sleeve 10 at its inner end is provided witha radial flange 1 2, best shown in Fig. 2, which has formed integrally therewith and projecting radially therefrom a pluralityof lugs 13 spaced unequal distances apart around the periphery of the flange.'V

` The wheel, designated generally by reference character 14, is provided with a hub 15 adapted to extend into the enlarged Core of the bearing box and to rotate loosely therein. The inner end of the hub is provided with an internal circumferential groove 16 adapted to receive the lugs 13 of the sleeve10,1` and the inwardly projecting flange 17 disposed in the groove 9 of the bearing box is pro vided with a plurality of longitudinally ex tending slots 18corresponding in number and spacing to the lugs 13 on the sleeve 10. It will be manifest that when the wheel is positioned so that each of the slots 18 is in longitudinal alinement with its respective lug 13 the wheel may be slid longitudinally into position on the axle whereupon a slight rotary movement of the wheel will cause the lugs 13 to engage behind the flange 17, thus locking thef wheel against longitudinal displacement in all positions except one, where the lugs and slots VVare disposed in absolute longitudinal alinement with each other. During the operation of the car the possibility of an lend pull upon a wheel at the exact instant that the lugs and slots are in alinement, so as to permit removal of the wheel, is infinitely remote, and consequently the wheel is for practical purposes securely locked to its bearing box against longitudinal displacement, while at the same time by having suitable marks upon the box and its wheel by which the wheel may be positioned to aline the slots and lugs ready removal of the wheel when occasion requires is ossible etween the inner end of the hub and the bottom of the groove 9 in the bearing box there is interposed a bearing washer 19 adapted to receive the inward end thrust of the wheel and since the outer end of the axle terminates short of the inner face 21 of the wheel hub no end thrust is imparted to the axle `but all end thrust is delivered directly to the bearing box through the washer 19. It should also be noted that the unequal spacing of the lugs andV their companion slots makes it impossible for the wheel to be removed except when it has been rotated to one definite position. INere the slots and lugs spaced equal distances apart the wheel might be removed in any one of three positions, which of course would increase the liability of accidental displacement.

In order to reduce the friction of rotation of the wheel to a minimum I have inter- Y posed between the axle and the wheel, roller Y surrounds the bearing rollers.

`withthe wheel and the bearing rollers remain in position on the projecting portion of the axle, where they may be inspected or repaired, if necessary, without any liability of their dropping out upon the dirty floor of the mine.

In Fig. 4; I have shown a slightly different mounting for the bearing rollers in which the sleeve 10 is extended outwardly approximately to the end of the axle providing a bearing sleeve 26 terminating at its outer end in a radial fla-nge 27 provided with a raceway for the outer ends of the bearing rollers 22, their inner ends being mounted similarly to what has previously been described in connection with Fig. 1. In this instance, however, the flange 27 being integral with the sleeve extension 26, cannot be removed for replacement of bearing rollers, consequently at one point the raceway is provided with a radial extension 28 through which the outer ends of the rollers may e introduced into the raceway proper in this flange 27. It will be manifest that in assembling the rollers the inner end of each roller is introduced into the raceway at the inner end of the bearing portion of the h ub, the wheel of course at this time being removed, whereupon the outer end of the roller is dropped through the groove or extension 28 into the raceway in the flange 27. All of the rollers may be assembled one at a time in this manner.

It will be manifest from the foregoing that I have provided in my car wheel a mounting in which the bearing rollers are always maintained in position on the axle when the wheel is removed, that the removal and replacement of a wheel may be quickly and easily accomplished when the wheel is properly alined with respect to its box, and that the overlapping relation of the box and inner end of the wheel hub protects the bearings against the entrance of dust and dirt which would cause them to wear rapidly and decrease their longevity.
